Give two characteristics of liquid state<br>​
inna [77]

Answer:  Liquids have the following characteristics: no definite shape (takes the shape of its container) has definite volume. particles are free to move over each other, but are still attracted to each other. liquids have lesser densities than solids.  Intermolecular forces of attraction is weaker than solids.  They have considerable space between the particles. Liquids flow from higher to lower level.  Liquids have their boiling points above room temperature, under normal conditions.

I gave many characteristics

Hope this helps :)

What can you tell me about the charge signs on the spheres
bazaltina [42]
<span>A similar thing occurred with the circles as did with the electroscope. When we initially brought the charged pole close to, the bar pulled in the circle since it was of polarization. At that point, once the bar touched the circle, the pole repulsed the circle. This is on the grounds that once the pole and circle touched, the electrons exchanged thus did the protons, consequently leaving the circle with a positive net charge. The nearer the bar is to the circle the more it repulsed, however, it didn't influence the charge of the circle once the circle was touched by the pole.</span>

Magnetite is a binary compound containing only iron and oxygen. the percent, by weight, of iron is 72.360%. what is the empirica
hram777 [196]
Answer is: <span>c. Fe</span>₃<span>O</span>₄<span>.
</span>ω(Fe) = 72,360%.
ω(O) = 100% - 72,36% = 27,64%.
For example, if we the mass of compound is 100 g:
m(Fe) = 72,36 g.
n(Fe) = m(Fe) ÷ M(Fe).
n(Fe) = 72,36 g ÷ 55,85 g/mol.
n(Fe) = 1,296 mol.
n(O) = 27,64 g ÷ 16 g/mol.
n(O) = 1,727 mol.
n(Fe) : n(O) = 1,296 mol : 1,727 mol.
n(Fe) : n(O) = 1 : 1,33 or 3 : 4.
